Answer:
occur naturally on earth .
Explanation:
Crude oil is found above natural gas reservoirs.
B.
Crude oil is found next to natural gas reservoirs.
C.
Crude oil is found below natural gas reservoirs.
D.
Crude oil is mixed in with natural gas reservoirs.
Answer: The correct answer is-
C. Crude oil is found below natural gas reservoirs.
Crude oil is a unrefined form of petroleum. Natural gas and crude oil both are nonrenewable sources of energy that are formed by remains of plants and animals that died millions of years back.
Natural gas is lighter as compared to crude oil. So natural gas has lower density as compared to crude oil. Due to this, crude oil is found below the natural gas reservoirs.
Thus, option C) is the right answer.
Answer:
Animal cell that does not have a cell wall.
Explanation:
Thus the animal cell does not have a cell wall.
In a food web, each step in the transfer of energy and matter is referred to as a trophic level. These steps provide an illustration of energy flow within an ecosystem, with examples being producers, consumers, and higher-level consumers. The transfer of energy - although more complex - is more accurately depicted in a food web than in a food chain.
The term for each step in the transfer of energy and matter within a food web is known as a trophic level. These are the different steps in a food web or chain at which the transfer of energy occurs. An example of these levels can include producers, primary consumers, and higher-level consumers, each playing specific roles in the overall energy flow.
A food chain is a linear system that offers a simplified view of energy transfer within an ecosystem, while a food web offers a more complex and holistic view of the multiple trophic interactions and energy transfers within an ecosystem.
It is important to mention that energy transfer efficiency influences the structure and dynamics of ecosystems. This is due to the fact that with each energy transfer, some energy is lost, often in the form of heat. This limits the length of food chains within a food web.
